Application led 'November 15,-9'10.' Serial 1N o.'-590-,898.

fore' it has been the common practice in concrete structures oit this character in building the necessary Wooden 'forms or molds, to connect the parts thereof with nails, lcleats a'nd the like, and in dismantling or dissociating the parts after the concrete has set,

considerable time is required and great Waste of lumber ensues.

The primary object of Ithis invent-ion is to provide simple and e''ec'tive means for V maintaining the association of the planks or mold boards without the use of nails or analogous fastenings and whereby the several parts of each mold may be expeditiously dissociated after the concrete has become set without loss 0i.z material or lumber, and Without breaking or mutilating the part molded, especially at the angular corners.

il further object of the invent-ion is to provide an organization of foiin or mold `inembers for conveniently constructing pillars or posts, girders land Hooi-s of concrete material in an integral manner within a building or other inclosu're, or to rforni con- 40 crete posts and girders integral Without. the

door if so desired.

-llVith these and other objects and advantages in view the invention consists in the construction and arrangement oi' the several parts ivli'ich will be more fully hereinafter described and claimed.

yThe numeral 5 designates a pest-dr lpillar I hield cr fermenti 6 a-grder ihold crrorin, there 'being as -ihahy posts and pillar nietes 0r iio'rni's 'used als ldesired and having* 'the garder Aforms or' molds rathaus-g rroi'nthe upper extremities ither-"cof `aitid in soihle v'instances extending from une pest Ior pinar form or mold' te another similar nicht, 1in order to produce a'ii integral concrete struc faire which may or may not include a freer of concrete in a inan'ner Which will beiiore fully hereinafter explained.

The post mold or form 5 is composedof a 'plurality of corner angle irons -7 'sind vboards or' planks 8, the latter `as shown 'being in pairs at each side, or in other Words each Wall of the mold or form 5 as illus trated embodiesltwo boards or Aplanks of different dimensions to accord with the size of post or pillar to be produced. Thenu'mber of planks or boards 8, however, is not essential, as they will be ino'ditx'ed in accordance with the various dimensions of posts or pillars constructed. The 'boards or planks constituting the side Walls' di the post mold or form, are of such Width as' to provide exterior corner spacesfat the adjatma ehe-Siae edges of the boards or planks 5% snugly abut against the outer surfaces oi the tvvo angular members of 'each' angle iron 7 adjacent to the angle ott said iron, as clearly shown by Fig'. 4, and said 'angle irons provide corner braces and supports and are connected' at regular intervals by cross or tie 'bolts vor 'rods 9 .which may be readily applied and removed, and vif'hen applied bear directly against the outerI sides of `the planks or boards as shovvnby Fig. 4. By nieans' of the disposition of the angle irons' 7 'as' just explained, said irons may be readily removed andv Withdrawn when released and the :boards or side Walls 8 may then be easily detached without injuring the corners of the 'post or pillar. By having the' tie rods' 9 closely bearing against the Walls, the laltte'r laire and are positively held in molding positions relatively to each other. The angular members 'of thel angle irons project outwardly beyond the outer surfaces oit the Walls 8', and the tie rods 9 directly engage said members, thereby d is- Y pensing with extra parts or structures for en agement by the tie rods.

tregular intervals throughout the length of each angle iron 7,' short stop or brace angles 10 are disposed and secured to the angle irons and also have bearing against the outer sides of the boards or planks to hold the'boards or planks in proper position between the angle irons 7 and to prevent out; ward bulging or springing lof the said boards or planks. The angle irons 7 near their upper terminals haveI angle iron knees or supports 11 adjustabl secured thereto for holding an open woo seat 12, the seat 12 providing a support for a girder box or mold, which will be presently explained, the angle iron knees 11 being adjustable through the medium of bolts and nuts 13 and a pluralfity of openings 111 in the angle members of the angle irons 7 to provide for constructing girders or beams of any depth desired. Inorder to accommodate the formation of posts relatively to varying distances be tween one fioor and a ceiling or between two iioors, a splice 15 will be used in connection with thelower end of the post mold or form, said splice consisting of angle irons similar to the irons 7 and connected by tie bolts or rods in 'the same manner. The parts of the post or pillar form or mold as thus described may be readily associated and dissociated without requiring the use of nails or Wasting lumber and providing-for the repeated use 'of the boards or planks constituting` the walls of the molds or forms and also the repeated use of the angle irons 7 at the corners of the post or pillar mold or form.

The girder molds or forms are arranged to intersect the upper extremity of the post or pillar mold or form and each comprises a bottom board 16 and side boards 17 adjoining the bottom 'board 1G at right angles.

" rl`he side boards or wall members 17 have channel iron standards 18 secured thereto at intervals and each formed with an upper seat 19 and a lower angular 'foot Q0. In the seats 1S) of the standards 18 angle iron joist supports 21 are secured. and thereon joists 22 are removably disposed for holding floor forms or boards 23, the ends of the joists fitting in the angle iron joist supports Q1 over the upper seats 10 of the standards 1Sv as clearly 'shown by liig. 2. The joists Q2 will extend from the angle iron seats or supports 21 to corresponding angle iron supports of other girder or beam molds or forms in accordance 'with the extent of the floor area which it is desired to produce. rl`he side boards or walls 17 ot' the girder or beam molds or forms are connected and supported by tie means, one of which is shown in Fig. 1 in the :t'ornL of a lie rod Jelhaving thereon a pipe spreader Q5 to jjirevent inward collapse ol' the said lside boards or walls 17. This form of tie means including the spreader 25 will be introduced only at the ends of the girder.

To give depth .to the girder orfbeam molds the latter are provided with supplemental side boards or walls 26 disposed edgewise on the upper edges'of the side boards or walls 17, the joints Q7 between, the walls 17 and QG being covered by the angle iron supports 21 and the said Walls 26 are partially`supported by the upwardly projecting members of the said angle iron supports. The side walls or boards 26 are positively held in removable` position relatively to the side boards or walls 17, but are maintained in lixed position when applied by clamping dogs 2S engaging the same at intervals and having upper vspiked ends temporarily driven into vthe outer sides of the boards or walls 26, as at 2S), and lower angular ends 30 which are engaged with the upper portions of the standards 18, as shown by Figs. 1 and 2. As many ot the dogs 28 will be used. .as may be found necessary throughout the length of the girder or beam Qmold. The giider or beam molds have their inner extremities projected inwardly between the flanges of the corner angle iro-ns 7 which are extended upwardly high enough to receive the said molds and at distances from the post orpillar mold 5 the girder or beam molds 6 have post-s 31 disposed thereunder at regular intervals and vcentrally engaging at their upper ends a bottom supporting j channel iron 32 extending transversely across and in contact with thel bottom boards 16 andlower edgesof the side boards or walls 17 and also under the feet 2O of the standards 18. At the angles of intersection of the feet 2() with the main bodies of the`- standards 18 loops are movably attached and indicated by the numeral 33, said loops being of such dimensions as to embrace and adjustably engage the bottom supporting channel iron or cross-head 32 on the post 31. The loops are Jforced inwardly When in locking position Iand caused to engage notches 34 cut inthe under edges of the supporting iron or cross-head 32 and operate to maintain the standards -18 and side boards or walls 17 in close engagement with and in upright position relative to the bottom boards 1G. By this'means a girder or beam mold that ma be readily assembled and dissociated wit iout waste ofvmaterial or injury to any of the parts thereof is provided, and when the parts of the mold are assembled they are. firmly held inoperative position by the fastening means or'dogs 28 and the fastening means or clamping loops 33 and supporting iron or cross-head 32.

If it is desired to form postsor pillars and girders or beams integralA therewith from concrete or analogous material withoift producing a floor slab as at 35, such incassi molding operation may be accomplished Without the use of the boards 23 and by simply filling the girder or beam molds and the portion of the post or pillar mold with which they intersect flush with the upper edges of said molds. In producing an integral floor slab orin forming the slab 35 integral with the posts and girder's or beams, the floor boards 23 are arranged over the 'joists 2Q and the concrete or other analogous material is spread thereover in any suitable or desirable thickness, as shown by Fig. 2 in full lines and indicated by dotted lines 4in Fig. l. In any event subsequent to the completion of the molding operation or after the concrete has become set, the posts 31 are removed and also the girder or beam molds from the completed girders or beams,

and the parts of the mold 5 are separated and withdrawn from the completed post or pillar. The parts ot the several molds or forms may then be again set up or reused, and When not in use they may be stored in compact form.
